Oh wait, there is a secret hook if you spelunk deep enough! Try this:

setHook(
  "rmarkdown.onKnitCompleted",
  function(input_file) unlink("plot.png")
)

How on Earth did you find this?!

Thank you!!

Since I just had to search Twitter to remember the secret sauce (😱) it would be better to have a short post about this on my blog
